APPARATUS FOR TRIMMING AND ELEVATING COAL AND THE LIKE.

Specification of Letters Patent.

Patented May 18, 1909.

Application filed September 5., 1908. Serial No. 451,913.

To all whom it may concern:

Be it known that I, ROBERT BROWN, a subject of the King of Great Britain and Ireland, residing at Liverpool, England, have invented certain new and useful Im rovements in Coal-Elevators, of which the Iollowing is a specification.

This invention relates to a new or improved method of and means for trimming and elevating coal and the like, the object being to provide a comparatively simple and efficient contrivance whereby, for example, coal or the like may be quickly and readily unloaded from a barge or the like and transferred to the hold of a vessel or other required place.

In carrying this invention into practical effect, it consists essentially of a scoop or shovel designed to dip into the coal with a scoop-like movement thereby raising` a certain quantity which it tilts into one of a convenient number of traveling receptacles which is raised 'to the required height, and in turn discharges its contents into a second shovel or the like which allows the coal to travel down a suitably arranged chute conveying it lto the required position. Suitable hammers or the like are arranged in conjunction with the device for breaking any large coal which might be encountered while means is provided for bringing the coal behind the scoop into position ready for the next stroke.

In order that this invention may be more fully understood, it will'now be described with reference to the accompanying drawings in which Figure l is a general diagrammatic view illustrating the manner in which this apparatus is employed for transferring coal from a barge to a ship, Fig. 2 is a front elevation of the lower part of the device constructed according to this invention, Fig. 3 is a side elevation thereof, Figs. 4 and 5 are similar views to Fig. 3 with the part in various positions, Fig. 6 is a diagram illustrating a cycle of movements hereinafter referred to. Fig. 7 is a similar view to Fig. 2 showing additional details of hammer mechanism hereinafter described. Fig. 8 is a detail side view of portions of the hammer mechanism, parts of the frame and the guide in being broken away. Fig. 9 is a side view of the discharging devices at the top of the elevator at the time the coal falls fromthe elevator bucket. Fig. 10 is a section taken on the line x-:r in Fig. 9. Fig. 1l is a side view of a portion of the frame and the revolving chute, showing the latter in a different position from that shown in Fig. 9.

As shown in the drawings, the shovel or scoop a is carried upon a crank a1 mounted in lbearings a2 at the lower extremity of a frame l), the crank shaft a3 being revolved throu 'h chains c and gearing c1 from a suitable riving pulley at the upper extremity of the frame lathe shovel or scoop a being furnished with a curved guide d designed to slide through a plate all so mounted that as the shovel of, commences its downward travel, as shown in Fig. 4, it is tilted upon the crank al into an approximately vertical position as shown in Fig. 3 and as the travel further progresses, and the shovel a passesthrough the coal, it is gradually returned to the horikzontal as shown in Fig. 5, thereby lifting a certain quantity of coal.

As the shovel is raised, one of a series of buckets or receptacles e carried by the endless driving chain c is brought beneath the front of the shovel aJ which, as it assumes the position shown in Fig. 4 deposits the coal into the bucket c which is lifted to the top of the frame l) and as it turns over the upper driving wheel, deposits its contents into a small chute c1 (Fig. l) carried bythe spindle of the upper driving wheel and revolving therewith, this small chute arriving at the position shown in Fig. 9 as the bucket tilts over, at which time the said bucket deposits its contents into the said chute which in turn discharges the coal which the bucket has deosited therein on to a suitably arranged main chute f (Fig. l) and the buckets e are so arranged upon the chain c as to come in turn beneath the shovel or scoop a at the moment the latter is ready to deposit its contents therein, while similarly the buckets reach the chute el at the :moment the latter is in a position to receivev their contents.

The shovel or scoop a carries on its under surface a series of claws g designed to engage the coal directly behind the shovel or scoop and bring it forward ready for the next stroke of the shovel as hereinbefore mentioned, these claws g also serving to facilicentrics 0,10 shown in the diagram, in Fig'f,r4

which illustrates live different positionsof the scooparound the crank-shaft.

Hammers h are provided to break up the large material. Each hammer 7L is carried by a bar h1 which slides in guides h2 secured Vto the frame l), see Fig. 8. A cord or chain t is secured to the top of eachhammer-bar and passes over a sheave i which is journaled in a bracket secured to 4a mounting j. The other end of the cord or chain is secured to a lbracket 0110 which is fastened to the frame l,

Vsee Fig.'4. The mounting y' slides between vertical guides t on the frame b. These guides are of any approved construction, and they prevent the mounting from moving eX- cept in a vertical direction. A sliding block jl is also slidable in the said guides below the mounting j, and is operated by a connectingrod apivoted to the said block at one end by a pin 2 and having its lower end pivoted to the shovel a by a pin k1.

The hammer and the .mounting j are raised by the upward movement of the 'block jl which pushes up the mounting. A springactuated catch ois pivoted at its middle part to the `frame b by a pin 01, and this catch retains the mounting and hammer in their raised position. A trigger p is pivoted to the 'frame b below the Vblock jl, and when the said block approaches the lower end of its travel it strikes this trigger, and moves the catch out of engagement with the mounting, thereby permitting the said mounting and hammer to descend suddenly by gravity.

Additional hammers, similar to the hammers h, may be operated by a sliding .member i2 secured to the sliding member jl and operating a sliding block r. The block r is attached to a YlieXible connection g which passes over a pulley Q1 and which is secured to a hammer in a similar manner to the connection 'i which is secured to `the vhammer 7L. The frame b is revoluble in an upper ,frame b1 from which it is suspended. The upper frame is supported by the derrick arm l. The small chute el is secured to the shaft I5 at the head of thev conveyer, see Fig. 9. A driving wheel 14 is secured on a shaft 15 which is ournaled in the frame b1 as shown in Fig. 10. A train of beveled toothed wheels 16, 17, y17 and 10, transmits the motion of shaft 15 to shaft 9 which is journaled inthe top part 11 ofthe frame b. The shaft Qhas It is preferred that the shovel or scoop a and claws g be lflexibly mounted in a a sprocket-wheel 8 secured on it, and a drivechain SIpasses over lthe wheel 8 and yover a sprocket-wheel 7 secured on the shaft 5. The shaft 5 is journaled in the frame b, and it has a driving drum or wheels 6 secured on it which operates the elevator' chains c.

The derrick m is mounted in a tender A which is secured on one side of the barge B which is toV be unloaded. The elevator may be driven from an engine in the tender A by means of a belt or drive chain/n. Y
